The gravitational force acting on the object, expressed as weight as a vector quantity. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others define it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight. As a result, the weight would be zero during free fall.
